Spock is being used to execute an integration test in a Spring Boot project (2.1.18.RELEASE). When I run with 1.3-groovy-2.5, I get this error:...
ANSWERAnswered 2022-Mar-28 at 21:40
java.util.ServiceConfigurationError: org.junit.platform.engine.TestEngine: org.spockframework.runtime.SpockEngine Unable to get public no-arg constructor
2.1.18.RELEASE is really old, it manages JUnit 5 to
5.3.2 while Spock 2.x requires >=
5.8. You can try setting
5.8.1 if you can't upgrade Spring Boot to a more recent version.
As for the type reflection error, we can't say much since you didn't share any code. Only that
com.foo.controller.ConversionsController.createConversionJob(ConversionsController.java:68) probably has some weird generics or is calling something that does.

Aside from updating the other dependencies to later versions and aligning groovy versions, which ought to resolve it, a quick fix is to declare a system property:

You can parallelise Spock testing on several levels, i.e. per specification (test class) or per feature (test method). The per-method setting also means that in iterated (unrolled) tests, iterations can run in parallel. Here is some proof:
We actually use
JUnit and the great
FakeSftpServerRule junit rule to test a custom SFTP client we made. That was working great.
Lastly, we want to get rid of junit in favor of the spock framework because we try to migrate to groovy.
Do you guys know any equivalent of
FakeSftpServerRule or any way to "switch" a junit rule into a spock rule equivalent ?
Thank you a lot....

The same author also published Fake SFTP Server Lambda, which is independent of the test framework in contrast to the JUnit 4 rule you use.
If you want to stick with the old tool, Spock 1.3 can also use JUnit 4 rules, and in Spock 2.x it might also work with the JUnit 4 compatibility layer.
Update: Here is an example program using the SSHJ library for downloading a file from an SFTP server, so we have a subject under test:
I know there are a bunch of similar questions on this topic, however all of them that I've found so far are either not quite my situation, or refer to one of the following solutions that from what I've read is either outdated or inapplicable:

- @Repository annotation - not needed when extending Repository interface

You are encountering a side-effect of Spock's magic.
Your method basically gets transformed to this:
I have a small problem. I have started writing tests for my small project. The project uses SpringBoot, standard JpaRepository from Spring, as a testing framework I am using Spock and for testing the database, I'm using PostgreSQL container from TestContainers. The problem is, that data between tests is being persisted, despite the @Transacional on each of the tests. The strangest part is, that in the logs I can see, that transaction is rolled back. I would appreciate any help.
So, these are the files:

ANSWERAnswered 2021-Dec-16 at 21:36
Your tests start an app that listens on a real port. And you use TestRestTemplate to make HTTP calls. It's the same as if you ran your test from a remote machine - would you expect
@Transactional on such tests to be some how applied to the app?
@Transactional will work only if you invoke your endpoint directly, without any network calls:
- either inject endpoint object directly to your test and call its method
- or use MockMvc (or RestAssured+MockMvc) - it will also eventually call the endpoint directly
Both of these options will simplify debugging - you'll be able to see in call stack which test is calling your production code at the moment.
PS: also it shouldn't be a problem when your data is kept between test runs. You can isolate your tests with randomization.
I'm trying to write a test for one of my controller classes. In this controller, I call
request.reader.text which can throw
MalformedInputException if the body contains non-utf-8 characters.
This is the case I'm trying to test and mock in my Spock test. The easiest would be if I could mock the
getReader() method, but that turns out to be difficult.

I finally managed to find a solution after some more frantic googling. Although, this is not as clean as I would have wished, it works!
The only way I've found it possible to manipulate the
response objects in a controller is by calling
RequestContextHolder.setRequestAttributes() with a new
GrailsWebRequest. The downside to this is that the response object also has to be overwritten. This is not a big problem however, as it is manipulated "in-place" when calling
render(), so we can just check the "would be" response status on our newly created object. My Spock test now looks like this:
I'm upgrading a Spring Boot application from 2.3.10.RELEASE to 2.4.12. The tests have been written with Spock 2.0-groovy-3.0.

The thing that breaks you code, is that mock interactions are the first thing that is evaluated in every
then block, even if you list other things first. So for it to work, you need to use a second
then block as explained in the chapter invocation order in the docs. Since, the mocks are evaluated first, the execution doesn't even reach
result.get() that would wait long enough so that the save interaction could be triggered.
This should fix your problem:

You can use spock like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the spock component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
